MULTIPLE PREGNANCIES AFTER INTRACYTOPLASMIC SPERM INJECTION (ICSI)

Zdravniški Vestnik, 2003
Background. Because of complications related to multiple pregnancies after in vitro fertilization this pathology represent a real problem. Intracytoplasmic sperm injection (ICSI) may lead to higher risk in developing monozygotic pregnancies. We sought to

Intrauterine administration of human chorionic gonadotropin does not improve pregnancy and life birth rates independently of blastocyst quality: a randomised prospective study

Reproductive Biology and Endocrinology, 2015
BackgroundSuccessful embryo implantation depends on a well-timed maternal-embryonic crosstalk. Human chorionic gonadotropin (hCG) secreted by the embryo is known to play a key role in this process and to trigger a complex signal transduction cascade ...

‘When Lightning Strikes Twice’—Preimplantation Genetic Testing for Two Indications in One Biopsy

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective We aimed to investigate whether the clinical pregnancy and live birth rates in women undergoing preimplantation genetic testing for two indications (PGT2) differ from PGT for one autosomal dominant indication (PGT1). Method This retrospective cohort study summarizes data from 44 PGT patients treated between 2015 and 2023.

A regularized MANOVA test for semicontinuous high-dimensional data [PDF]

arXiv
We propose a MANOVA test for semicontinuous data that is applicable also when the dimensionality exceeds the sample size. The test statistic is obtained as a likelihood ratio, where numerator and denominator are computed at the maxima of penalized likelihood functions under each hypothesis.

TWIN PREGNANCY AFTER THE TRANSFER OF TWO EMBRYOS

Zdravniški Vestnik, 2003
Background. Twin pregnancy rates following the transfer of two embryos in in vitro fertilization (IVF) treatment are high. Therefore, the aim of this study was to evaluate twin pregnancy rates in regard to the developmental stage of the embryo, patient ...

HIPPO Pathway Members Restrict SOX2 to the Inner Cell Mass Where It Promotes ICM Fates in the Mouse Blastocyst

PLoS Genetics, 2014
Pluripotent epiblast (EPI) cells, present in the inner cell mass (ICM) of the mouse blastocyst, are progenitors of both embryonic stem (ES) cells and the fetus.
